This bug report is a parity issue with Java.

Summary:
Hitbox warped fungus not the same as in java versions.
Java: 9 pixels high and 8 pixels on the sides (4 pixels off the edge).
Bedrock: ~9,1 pixels high and 7,5 pixels on the sides (~4,1 pixels off the edge).
*in the bedrock version, the hitbox is imprecise as it does not split the pixel.
It is necessary to increase the sides to a pixel, and reduce the height (also so that there is a whole pixel).

Steps to reproduce:

1. Place warped fungus.
2. Take a look at the dimensions of the hitbox.

Observed results:
The hitbox starts and ends not at the edge of the pixel, but at its beginning.

Expected results:
The hitbox of the blocks must be the same.
